Determine the boiling point of a solution contanting 36.1grams calcium chloride molar mass 112 in 200.0grams water.

Answer 1

mols CaCl2 = grams/molar mass
Substitute and solve for mols.

molality = mols/kg solvent
Substitute and solve for m.

Then delta T = i*Kb*m
i = 3 for CaCl2.

Answer 2

Forgot. The problem asks for the boiling point. The above calculate delta T. Add delta T to normal boiling point for new boiling point.
